I've run into this issue a couple of times, but previously hesitated to report it as it's pretty tough to reproduce. I'm getting an error on compilation of my game "Error enumerating items: Corrupt resource header - mismatched types." For context, I was working on modifying a script - no other resource manipulation activities.
Game is SCI 1.1, I'm running version 3.2.3.2, Kawa's build.
EDIT: The quick-fix for this was to discard my resource file and map and recompile everything, which was viable for me because I hadn't introduced any other resources since my last commit.
